A ventilation system from STIEBEL ELTRON means your living comfort and wellbeing are covered. [H2] A comfortable atmosphere: the result of good indoor air What affects our room climate? First, of course, there is the weather: summer heat, dry cold, humid conditions. Fine dust and pollen can get into your home when you open the windows. And you, too, have an impact. After all, you breathe, cook, clean and shower, exhaling carbon dioxide into the indoor air, creating an abundance of scents and smells, and emitting heat and water vapour. A three-person household emits up to ten litres of water per day in the form of water vapour into the indoor air. And emissions from building materials, furniture and floors can also have a negative impact on your indoor air. Perhaps you like to linger in the bath, sleep in late or cook three-course meals? Your ventilation system ensures good, healthy air in your home at all times. The logical consequence is that the air must be replaced regularly. If it is not, the oxygen content of the air drops while the amount of CO2 and harmful substances it contains increases. And excessive concentration of carbon dioxide in indoor air has been shown to cause discomfort, as well as to negatively affect cognitive performance. And none of us want that... the solution is a ventilation system that works fully automatically to ensure greater living comfort and a better atmosphere in your home! [H2] Here’s all you see of your new ventilation system in your living room and bathroom The LA 70 decentralised ventilation unit is suitable for ventilation all extract air areas with an external wall and can be used for different safety zones in sanitary facilities.

The video below shows you how to replace the filters in your VLR 70 ventilation system. Suitable spare filters and filter sets for your ventilation system can be sourced from our partners. Benefits for your home Discover high grade filters for even better indoor air quality We offer you a broad variety of filter classes Reduce fine dust and pollen High dust holding capacity Explained in brief [H2] How does a ventilation system work? We offer both central and decentralised ventilation systems. Read on to find out how each type works. [H2] How a decentralised ventilation system works When it comes to ventilation systems, we differentiate between decentralised and central units. An air distribution system is not needed for decentralised systems. They are therefore especially suitable for retrofitting in a modernisation project. We offer systems with and without heat recovery: in the case of decentralised systems with heat recovery, your installer puts a single unit in the external wall of each room to be ventilated. This may involve systems with two fans and heat recovery via a countercurrent heat exchanger, for example. Moreover, you can use units also known as reversible fans. These are always installed in pairs and run alternately so that no underpressure or overpressure is created in the room. If required, you can operate up to eight ventilation units by means of one control unit and one programming unit. Through regenerative heat transfer, the high quality aluminium heat exchanger is charged with heating energy from the extract air. The EC fan changes direction after 40 seconds and blows fresh air from the outside into the room. As this happens, the previously absorbed heating energy is transferred to the supply air. This reduces heating energy loss by up to 93 percent. [H2] How central ventilation systems work Central solutions used in new build or comprehensive modernisation projects are available as extract air systems and as supply/extract air systems. These require ventilation ducts that are let into walls, concrete ceilings, suspended ceilings, the floor, placed under a screed layer, or even kept visible. An extract air system extracts stale air via ductwork from the extract air areas, such as the kitchen, bathroom and toilet. At the same time, fresh air is drawn through outdoor air apertures directly into the supply air areas (living room, play room, bedrooms). The volume of air extracted from the extract air areas is determined by the fan rate. A supply/extract air system draws the outdoor air from a central point and distributes it by means of ductwork throughout the supply air areas. Heat is recovered in a cross-countercurrent heat exchanger, which transfers up to around 90 percent of the latent heat in the extract air to the supply air. The outdoor air is filtered to prevent contamination of the unit and ductwork, and to protect allergy sufferers against the effects of dust and pollen. [IMG: LWZ 180 ventilation system from STIEBEL ELTRON] LWZ 180/280 central ventilation systems are a good choice for apartments, detached houses and commercial properties of up to approx. 170/250 square metres. Tip: if your indoor air is very dry, an enthalpy heat exchanger will help. [IMG: LWZ 8 CS Premium ventilation system from STIEBEL ELTRON] The LWZ 8 CS Premium central integral ventilation unit offers every comfort and convenience worthy of an energy efficient house. It reliably takes care of your living comfort, with ventilation, room heating, DHW heating and cooling functions. Moreover, some ventilation systems with heat recovery can include an enthalpy heat exchanger. This not only recovers the latent heat from the extract air, but also some of the moisture, and transfers these to the supply air. In conventional heat exchangers, the air streams are routed separately past each other through extremely thin plastic or aluminium walls. The heating energy flows automatically from the warm exhaust air to the cold supply air. Enthalpy heat exchangers use a permeable membrane – that allows even water vapour to pass – between the air streams. This transfer also takes place automatically as soon as dry air and “humid” air are routed past each other on either side of the membrane. [H4] Downloads [H3] Compact knowledge.

Your Diagnosis
Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.
Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)
These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.
Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.
Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.
Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.
Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.
Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.
Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

Industrial, Manufacturing & Engineering BS: STIEBEL ELTRON (stiebel-eltron.com)
STIEBEL ELTRON is a legitimate engineering entity using ‘German Engineering’ as a brand shield, but they back the shield with genuine technical depth. The site avoids most low-level marketing BS by providing actual mechanical explanations for their products rather than just lifestyle benefits. It is a product-led site that prioritizes technical utility over aggressive marketing fluff.
Implement comprehensive Organization and Person schema on the homepage to link Dr. Kai Schiefelbein and the brand to verified external entities. Replace the generic ‘German Engineering’ H2 with specific ISO 9001 or ISO 14001 certification numbers and the names of the certifying bodies. Add direct links to independent test results (e.g., TUV or equivalent) next to efficiency claims like ’93 percent’ to convert assertions into verified proof. Transform the ‘Projects’ mentions into deep-dive case studies with named commercial clients, specific site metrics, and pre- vs. post-installation energy data.
The website perfectly aligns with the Industrial, Manufacturing & Engineering category, specifically focusing on building services, HVAC, and renewable energy systems. The presence of technical specifications, product model numbers like LWZ 8 CS Premium, and mechanical descriptions of heat exchangers confirms its manufacturing focus.
“The BS score of 32 is primarily driven by the 'Identity and Authority' pillar (missing homepage schema) and the 'Commodity Fingerprint' pillar (heavy reliance on the German Engineering trope). Information density and semantic coherence are exceptionally strong, preventing the score from entering the 'Moderate BS' range. The site is a rare example of an industrial firm that delivers the technical substance promised by its high-level branding.”
